Insulating a flat roof with PUR foam is one of the most effective methods of insulation to improve the thermal performance and supports the waterproofing of the roof, helping to protect against damp and weather. A properly selected insulation layer reduces heat loss from the building and protects it from overheating in summer. Even a small thickness of Pur foam protects against condensation under the roof slope.

The PUR foam insulation layer on a flat roof is lightweight, permanently bonding to the substrate to form a tight barrier without thermal bridges. One of the advantages of this technology is the thorough sealing of components such as chimneys, firewalls and ventilation infrastructure.

Depending on the requirements in the building to be insulated, the thickness of flat roof insulation used is 3-12 cm.

Insulating a flat roof with PUR foam requires a great deal of experience, so the choice of contractor should be determined mainly by their competence and not by price.
